SPRAYlNG DEVICE FOR TOBACCO-CASING MACHINES.

SPECIFICATION forming part of Letters Patent No. 519,425, dated May 8, 1894. Application filed June 12. 1893. Serial No. 477,255. (No model.) Patented in Canada November 1892, No. 40,922.

To aZZ whom it mar/ concern:

Be it known that I, JOHN C. FROST, a citizen of the UnitedStates, residing at Winston, in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in Spraying Devices for 'lobacco-Oasing Machines, (a patent for which was granted to me in Canada. November 5,

y 1892, No. 40,9223 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to a spraying nozzle for a tobacco casing machine which delivers the sweetening or avoring fluid to tobacco during the casing operation in the form of a sheet spray, the spray of the iavoring fluid being capable of being regulated as will be hereinafter described and claimed.

In the accompanying drawings Figure 1 is a longitudinal section of the casing drum or reel, the screening drum and the spraying device. Fig. 2 is a side elevation of the spraying device.y Fig. 3 is a vertical section through the same. Fig. 4 is a transverse section through the line a: a: of Fig. 2. Fig. 5 is a transverse section through the spraying device with the vertical adjustable bar or gate removed. Fig. 6 is a side elevation of a slightly modified form of the spraying device, the sliding bar or gate being dispensed with. Fig. 7 is a vertical section through the` same. Fig. 8 is a detail plan view of regulating plate shown in Fig. 7 and Fig. 9 is a detail plan view of the deiector shown in said figure.

A` in the drawings as shown in Figs. 2 and 3, represents the body of the spraying nozzle, B a spray regulating plate,C a deliecting cap and C a sliding cleaning gate or bar forming a part of the deflecting cap, the parts being secured together by screws -Z, Z, as shown. The body of the nozzle has a centralpassage c which connects with a iavoring liquid conducting pipe D as shown. y,

The spray regulating device B consists of a plate provided with two or more .diverging holes b, b, of dierent sizes for the purpose of regulating the spray as will be hereinafter described. The sliding bar of the detlecting cap is formed with a flaring diverging orifice .c which when the cap is applied to the spray regulating plate, forms a spreading opening for the discharge of the sweetening mixture. By removing the screws Z,Z thespray regulating plate can be so turned that when the parts are properly united again, the spreading discharge opening c will register or communicate with any one of the holes b desired, sothat the spray can be readily and quickly increased or diminished. The cleaning sliding bar or gate C consists of a V or other suitably shaped piece which is held in contact with the body portion of the cap C by a fastening band as E which is formed at its lower end with anupwardly and outwardly flaring discharging orifice c which forms a deiector for the discharge of the flavoring liquid. By making the bar `or gate, V or wedge shaped, the inner edge of the same is brought to the centerof the cap and permits the liquid to diverge and spread from said point to the circumference of the daring orifice.

The sliding bar or gate is for the purpose of freeing the innerend of the daring orifice c from any sediment or matter which may have collected there and would clog the same and obstruct the discharge of sweetening liquid, and this is accomplished by raising the sliding bar or gate by means of the screw F, which latter is provided with a collar f and Works in a recess c3 in said bar, whereupon by turning the screw, the sliding bar can be adjusted as desired and the clogging matter is free to be forced out by the discharging liquid.

Figs. 6 and 7 show a modification in my spraying nozzle which consists of a main part or body A provided with a threaded orifice a to receive the pipe upon which it is to be used,'which orificeterminates in a smaller orifice d, as shown; a regulating plate B having two or more diverging orifices b b2 of different sizes and a cap deflector c2 having a spreading groove O3. The body A', plate B and capO2 are secured together by. bolts Z Z and the plates are so arranged that the groove C3 lies over and communicates with either of the oriticesb b2 with which it is desired to be used. By unscrewing the bolts Z Z', and changing the position of the plate b', any desired orifice may be brought into use in connection with the groove C3.

What I claim ,isj 1. In a spraying nozzle for atobacco casing machine, the combination of a main body portion, a cap provided with a dischargeoritice and capable of 'adjustment to vary the size of said orifice, a spray regulating disk provided `with discharge passagesof different diameters, saiddisk being capable of rotation and` adjustment concentrically with the-body of the nozzle, and means for locking the disk inl different `positions when the different sized openingsarebroughtin alignment with the discharge orifice, substantially as set forth.

2. In aspraying `nozzle `for tobaccocasing machines, the combination of a main body po`r tion provided `with a `central screw-threaded aperture, atdisk provided with divergingap-l ertures, and a deflectingcap provided with? `a spreading `groove on its under side; said diskand cap being so arranged that when` one of the apertures corresponds invposition,

with said spreading groove, it will produce a fan like spray, substantially asset forth.

3. In a spraying nozzle for a tobacco casing machine, the combination of a main body portion, a spray regulating plate a cap portion therefor `comprising a vertically adjustable bar or gatefor freeing the nozzle of obstructing matter provided at its lower end with a deiiectingdischarge oriiice which communicates with an openingin the regulating plate, substantially as described.

4. In a sprayingdevice for a tobacco casing machine, the'combination of a main body p0rtion, a `spray regulating plate a cap portion, a vertically adjustable gate or bar provided at its lower end .with ,an outwardlyand upwardly Haring discharge opening which communicateswith `an opening in the cap portion, anda screw for raisingand lowering the said bar or gate, substantiallyas described.

.In` testimony whereof I hereunto affix my signature in presence of two witnesses.
